SELF-CLOSING COCK OR FAUCET.

SPECIFICATION forming part of Letters Patent No. 556,133, dated March10, 1896.

Application filed February 2, 1893. Serial No. 60,719. (Model) To allwhom it may concern.-

Be it known that I, WILLIAM BUNTING, Jr. a citizen of the United States,and a resident of Flushing, in the county of Queens and State of NewYork, have invented certain new and useful Improvements in Self-ClosingCocks orFaucets, of which the following is a specification.

My invention relates to that class of selfclosing cocks or faucets inwhich the supplycontrolling valve seats or closes with the pressure ofthe liquid, and has for its main object to provide a constructionwhereby all shock, reaction, or water-hammer in the seating of the valvemay be avoided or eliminated, thus overcoming a serious objection tothis class of contrivances.

My invention consists in certain features of construction andcombinations of devices, all as will be hereinafter more fullydescribed, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a central vertical section ofa cook or faucet embracing my improvements. Fig. 2 is a horizontalsection thereof, taken at the line 00 a: of Fig. 1. Fig. 3 is across-section taken through the ports of the supplemental valve.

Fig. 4: is a modification of the supplemental valve, and Fig. 5 is amodification of the escape-passage.

In the several views the same part will be found designated by the samenumeral of ref erence.

I have shown my improvements embodied in a well-known form orconstruction of selfclosingbasin-cocks; but it will be understood, ofcourse, that the same may be carried out in other forms or constructionsof cocks.

1 designates the shell or casing of the cock; 2, the'water-inlet; 3,the'spout or nozzle, and 4 the water-outlet.

5 is a vertical spindle, having a handle 6' teriorly to receive packing11 and a gland or follower 12, which surrounds the spindle.

13 is a plate or cross-piece, which is supported upon a cylindricalledge 14 in the shell or casing and serves as a rest or abutment for thelower end of a coiled spring 15, surrounding the spindle, and whoseupper end presses against the under side of the gland or follower.Bythis construction the spindle is kept properly packed, and any escapeof water at the upper end of the cap 10 is effectually prevented.

16 is the main or supply-controlling valve, which may have a rubber orleather or other facing 17, adapted to a valve-seat 18, formed in theshell or casing.

19 is a cap or head screwed into the casing and forming interiorly avalve-chamber 20. Within this chamber is a coiled spring 21, adapted towork with the pressure in forcing the valve 16 to the seat 18. a

In the shell is formed a circular opening 22, through which passes avalve-stem 23 having four radial wings which bear at four points onthewall of said opening and serve to guide the valves in opening andclosing. From this valve-stem extends a loop or frame 24, in the opening25 of which is arranged the crank 0r offset 9 of the spindle. From theloop or frame extends a supplemental valve 26, preferably made in theform of a plug or piston, and consisting of a cylindrical portion 27,which is adapted to a circular thick ring or elongated bearing 28 in thespout or nozzle, and an extension provided with ports or passage-ways29. The valve-stem 23, the frame 24:, and the valve 26 are preferablyall cast in one piece, and the valve 16 is preferably screwed onto itsvalve-stem. Between the valves 16 and 26 is a chamber or space 30, inwhich the valve-stem, the loop or frame, the valve 26, and the crank 9are accommodated and adapted to Work.

The diameter of the ring 28 is slightly greater than that of thecylindrical portion of the valve 26, to form an escape-passage 31, for apurpose which will presently appear.

In the several views the valve 16 is shown closed or as firmly upon itsseat. If the handle be now turned the said valve will be moved towardthe left or back against the force of the spring 21 and thewater-pressure, and the water will pass by the valve and valve-stem intothe chamber or space 30, and if the valve 16 has been opened to its fullextent the cylindrical portion 27 of the supplemental valve will havebeen slid into the chamber 30 to an extent such as to bring the ports 29into communication with said chamber, and thus permit the free egress ofthe water therefrom into the spout or nozzle discharge-passage 4. Theparts are so arranged or constructed as that the valve 26 will not beopened or have its ports brought into communication with one until thevalve 26 closes or registers with its seat or bearing, and which occursbefore the main valve reaches its seat, or when it is about half-wayback to its seat. As soon as the valve 26 thus closes it acts to retardthe closing of the main valve, which moves always with and at the samevelocity as the supplemental valve. After the latter closes or comesinto alignment with the elongated ring or bearing it continues to moveforward or to advance farther, but more slowly, and hence the finalclosing movement of the main valve is gradually effected. During theclosing of the valves a portion of the water escapes through the smallpassage between the supplemental valve and its seat, and also after thevalves are both closed.

It will thus be seen that if the valve 16 is opened to its full extentthere may be a full and free discharge of the water at the nozzle, andthat upon releasement of the spindle the valve 16 will move toward itsseat under the pressure of the spring and force of the water, but saidmovement of said valve will be retarded or restrained as soon as theportion 27 is brought into alignment with the ring or wall 28. The valve16 is thus cushioned and compelled to seat gradually, and thus all shockor water-hammer in the pipe or passage-ways is effectually prevented,and it will also be seen that if the valve 16 is only partially openedand then suddenly released the same retarding action and cushioningeffect will be produced.

At Fig. 4: is shown a valve 26 entirely cylindrical and which fits thering or bearing 28 loosely, as above explained. Instead however, ofmaking the ports 29 as shown at Figs. 1, 2, and 3, they are formed by acentral longitudinal opening in the valve and by one or more transverseperforations therein meeting the longitudinal opening. The operation ofthis construction is substantially the same as that already described.

The escape-passage 3 1 for the water, formed between the parts 27 and 28in Figs; 1 and 4, may of course be located or arranged at other portionsof the fixture.

At Fig. 5 the by-pass or escape-passage 31" is formed in a fixed in lieuof amovable part of the faucet, and preferably through the wall of thering 28 The escape-passage may consist of one or more perforations, asshown. 111 this construction the valve 26 may fit snugly, (yet not tooclose to prevent its working freely,) so as not to permit the escape ofthe water in the manner described, of the construction shown at Figs. 1and 2, although there may be a slight leakage therethrough,

owing to the difiiculty of forming a perfectlytight joint or bearingwithout packing, the use of which I prefer to avoid. From thisconstruction it will observed that upon the releasement of the handleand the aligmnent of the cylindrical part 27 of the valve 26 with thering 28 the free discharge of the water is cut off, and that a portionof the body of water between the valve 26 and the valve 16 must beforced or driven past the former through the escape-passage 3l"beforethe valve 16 can seat, and the escape 31 being comparatively small thevalve 16" is retarded and caused to seat slowly.

Numerous other changes in detail construction of the various parts maybe made without departing from the spirit of my invention.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a self-closing faucet, the combination of a mainsupply-controlling valve, a supplemental diseharge-valve, and anintermediate water-chamber, said valves being integrally connected tomove always together, the said main valve being arranged to open beforethe supplemental valve moving in unison therewith entirely leaves itsseat or bearing, and the supplemental valve being arranged to seat andclose the discharge-passage in advance of the main valve and to servethereafter to efiect a retardation in the closing movement of the mainvalve.

2. In a self-closing faucet, the combination of a mainsupply-controlling valve, a valveehamber and a valve-seat therefor, thesupplemental piston or plunger valve rigidly connected to the mainvalve, a discharge-outlet controlled by the piston or plunger valve, anelongated seat or hearing for said plungervalve, whereby after closingthe latter may continue to move and control and retard the finalmovement of the main valve, and a water-chamber between the main valveand the piston or plunger valve.

3. In a self-closing faucet, the combination of a mainsupply-controlling valve, a valvechamber and a valve-seat therefor, asupplemental valve rigidly or integrally connected to the main valve, adischarge-outlet controlled by the supplemental valve, a waterchamberintermediate the said Valves, and an escape-passage from saidintermediate water-chamber to said discharge-outlet, through which thewater may pass both when the valves are open and when they are closed.

4. In a self-closing faucet, the combination of a mainsupply-controlling valve closing with the pressure, a spring acting toforce said valve toward its seat, a valve-chamber for said valve, asupplemental valve, a valvestem, to one end of which the main valve isattached, and to the other end of which the supplemental valve isattached, so that both valves move in unison, a discharge-outletcontrolled by the supplemental valve, a waterchamber intermediate saidvalves, an escapepassage from said water-chamber to saiddischarge-outlet, and means for opening said valves simultaneouslyagainst the pressure of the water and the spring.

5. In a self-closing faucet, the combination of the valve 16, thevalve-seat and chamber therefor, the valve-spring, the valve-stemcarrying at one end the valve 16 and at its opposite end the valve 26and provided between said valves with a loop or frame, thedischarge-outlet for the supplemental valve, the water-chamber betweensaid valves and in which the loop or frame works, the spindle passinginto said water-chamber, and the crank on said spindle in operativeengagement with said loop or frame.
